Abstract
We propose the interval grey uncertain linguistic correlated ordered arithmetic averaging (IGULCOA) operator and the induced interval grey uncertain linguistic correlated ordered arithmetic averaging (I-IGULCOA) operator based on the correlation properties of the Choquet integral and the interval grey uncertain linguistic variables to investigate the multiple attribute group decision making (MAGDM) problems, in which both the attribute weights and the expert weights are correlative. Firstly, the relative concepts of interval grey uncertain linguistic variables are defined and the operation rules between the two interval grey uncertain linguistic variables are established. Then, two new aggregation operators: the interval grey uncertain linguistic correlated ordered arithmetic averaging (IGULCOA) operator and the induced interval grey uncertain linguistic correlated ordered arithmetic averaging (I-IGULCOA) operator are developed and some desirable properties of the I-IGULCOA operator are studied, such as commutativity, idempotency, monotonicity, and boundness. Furthermore, the IGULCOA and I-IGULCOA operators based approach is developed to solve the MAGDM problems, in which both the attribute weights and the expert weights are correlative and the attribute values take the form of the interval grey uncertain linguistic variables. Finally, an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness.
Highlights
Multiple attribute group decision making (MAGDM) has been extensively applied to various areas such as society, economics, management, and military
Motivated by the correlation properties of the Choquet integral and the uncertain linguistic variables, in this paper, we propose the interval grey uncertain linguistic correlated ordered arithmetic averaging (IGULCOA) operator and the induced interval grey uncertain linguistic correlated ordered arithmetic averaging (I-IGULCOA) operator with interval grey uncertain linguistic variables information
The aim of this paper is to investigate the multiple attribute group decision making (MAGDM) problems, in which both the attribute weights and the expert weights are correlative and the attribute values take the form of interval grey uncertain linguistic variables
Summary
Multiple attribute group decision making (MAGDM) has been extensively applied to various areas such as society, economics, management, and military. Those operators consider the importance of the elements, and can reflect the correlations among the elements They developed an approach to multiple attribute decision making problems with correlative weights where the attribute values are given in terms of interval grey linguistic variables information based on those operators.
